the data analyzing and processing module 22 is configured to use the real-time user experience index and the media service transmission parameter as input of a formula f(priority)=(MOS_(o)−MOS_(C))*Po*f(t, rate, rate variance), to calculate the radio channel parameter that is required by the user experience index defined in the user experience level, where:

Bandwith_(o) indicates a radio channel bandwidth defined in the user experience level, MOS_(o) indicates a user experience index defined in the user experience level, MOS_(C) indicates a real-time user experience index, Po indicates a radio channel scheduling priority defined in the user experience level, f(t, rate, rate variance) indicates an incremental calculation function, t, rate, and rate variance indicate respectively a time length of a media service, an average rate of accessing the media service, and a variance of the average rate that are included in a media service transmission parameter, f(bandwith) indicates a radio channel bandwidth that is required by MOS_(o), and f(priority) indicates a radio channel scheduling priority that is required by MOS_(o). For example, f(t, rate, rate variance) may be implemented by using a product of t, rate, and rate variance, or f(t, rate, rate variance) may be implemented by using a product of t and rate variance.

In this embodiment of the present invention, the network status module 26 is further configured to: before collecting the real-time user experience index for access to the media service provided by the server by the UE in the defined time period of the ordered traffic package, collect a real-time user experience index for access to the media service by the UE in a defined time period of a current traffic package; when the real-time user experience index for access to the media service by the UE in the defined time period of the current traffic package is less than a preset user experience index, obtain a media service type of the media service provided by the server; and obtain a user experience level of the current traffic package and a radio resource utilization rate of a wireless base station to which the UE belongs.

Correspondingly, the data analyzing and processing module 22 is further configured to: when the radio resource utilization rate of the wireless base station to which the UE belongs is higher than a preset radio resource utilization rate, compare whether a user experience level that is required by the media service type is higher than the user experience level of the current traffic package; and if the user experience level that is required by the media service type is higher than the user experience level of the current traffic package, search for a to-be-ordered traffic package meeting the user experience level that is required by the media service type.

Correspondingly, the network control module 23 is further configured to recommend the to-be-ordered traffic package to the UE.

In this embodiment of the present invention, the radio resource utilization rate may include an air interface utilization rate.

In this embodiment of the present invention, a business management point (Business Management Point, BMP) of the billing system 27 may provide a Web interface to communicate with an external unit, and a convergent billing point (Convergent Billing Point, CBP) of the billing system 27 may be configured to record a traffic package of the user, a traffic usage situation, and a deduction; in addition, the convergent billing point may communicate with a GW to notify information such as the traffic usage situation and the deduction situation of the user.

In this embodiment of the present invention, the network control module 23 of the traffic trading platform may send the user traffic package update information including information about the ordered traffic package to the BMP of the billing system 27; after receiving the user traffic package update information, the BMP may send the user traffic package update information to a CBP; the CBP updates, according to the ordered traffic package, the stored traffic package of the user and the stored traffic package of the seller of the ordered traffic package; and the CBP deducts, from the account of the user, the order amount corresponding to the price of the ordered traffic package, and adds the order amount to the account of the seller. Further, the CBP may feed an updated traffic package of the user and an updated traffic package of the seller of the ordered traffic package to the GW and the traffic trading platform (for example, a VNO platform).

As an implementation manner, the network control module 23 may be configured to limit, according to the radio resource utilization rate of the wireless base station, the number of orderable traffic packages with a high user experience level, and specify a defined time period and a use location that are of the to-be-ordered traffic package, to ensure a user experience requirement corresponding to the to-be-ordered traffic package; if the number of traded traffic packages is less than the number of orderable traffic packages, the API interface module 24 may receive the traffic package query request sent by the user terminal.

The foregoing describes the network architecture and the traffic trading platform (for example, a VNO platform) in the embodiments of the present invention, and the following further describes a method disclosed in an embodiment of the present invention. In this embodiment of the present invention, a user may access a VNO platform to complete a trading process of a traffic package. When needing to order another available traffic package, user A needs to first confirm a parameter of a to-be-ordered traffic package, where the parameter includes a size, a defined time period, a user experience level, a price, and the like that are of the traffic package, and the user experience level reflects service assurance provided by a wireless network to the user, and may be an MOS score, a network quality of service (QOS) value (for example, a bandwidth or a delay), or a scheduling priority. The user experience level is mainly reflected by a service experience difference when a user accesses a media service (for example, watching a video) by using a wireless network. For example, for a user with a high user experience level, the wireless network can ensure that the user can watch a high-definition video online smoothly at any time without such situations as pausing and garbling, which affect subjective perception; and for a user with a low user experience level, user experience cannot be ensured in a case of network congestion; and a worst situation is that a user may not be able to access a media service when a network is relatively congested (with simultaneous access of a relatively large number of users).

Referring to FIG. 3, FIG. 3 is a schematic flowchart of a traffic package trading method disclosed in an embodiment of the present invention. The method shown in FIG. 3 is described in terms of a VNO platform. The traffic trading platform in the foregoing embodiment may be configured to implement the method, and corresponding modules of the foregoing traffic trading platform may be configured to execute specific steps or configured with specific functions. As shown in FIG. 3, the method may include the following steps:

301: A VNO platform receives a traffic package query request sent by a UE, where the traffic package query request includes a to-be-ordered traffic package parameter, and the to-be-ordered traffic package parameter includes a size, a defined time period, a user experience level, and a price that are of a to-be-ordered traffic package; the to-be-ordered traffic package parameter may further include a use location; and the UE may send the traffic package query request to the VNO platform by using an API interface module provided by the VNO platform. For example, in a more specific embodiment, the traffic package query request includes a to-be-ordered traffic package parameter, and the to-be-ordered traffic package parameter includes a defined time period for use of a to-be-ordered traffic package or a user experience level of the to-be-ordered traffic package.

302: The VNO platform performs identity authentication on the UE, and if the identity authentication succeeds, queries a traffic package in conformity with the to-be-ordered traffic package parameter, and sends the traffic package to the UE, where an authentication and management module of the VNO platform may query registration information of the UE, and perform identity authentication on the UE according to the registration information of the UE. For example, more specifically, the VNO platform performs identity authentication on the user terminal, and if the identity authentication succeeds, queries a to-be-ordered traffic package in conformity with the to-be-ordered traffic package parameter, where the to-be-ordered traffic package is in conformity with a requirement of the defined time period or the user experience level, and sends the to-be-ordered traffic package to the user terminal.

303: The VNO platform receives an ordered traffic package sent by the UE, where the ordered traffic package is a traffic package of the to-be-ordered traffic package in conformity with the to-be-ordered traffic package parameter. Specifically, for example, the ordered traffic package is a traffic package selected by the user terminal from traffic packages in conformity with the to-be-ordered traffic package parameter, where the ordered traffic package is used in the defined time period, or the user experience level is obtained when the user terminal uses the ordered traffic package.

In this embodiment of the present invention, the VNO platform may further confirm legality of the ordered traffic package, which includes checking whether an ordering user meets a purchase condition (a payment mode, an account balance, or the like) and whether the ordered traffic package has been sold; and may even confirm to a CN whether information about the ordered traffic package is accurate. Package information and tariff information of the user are recorded in a user status module of the VNO platform, and may be used to confirm the legality of the ordered traffic package.

In this embodiment of the present invention, the VNO platform may further send an order confirmation notice to both parties of the trading or to only the buyer, and receive information that is fed back by the buyer.

304: The VNO platform sends user traffic package update information including information about the ordered traffic package to a billing system, so that the billing system updates, according to the ordered traffic package, a stored traffic package of the user and a stored traffic package of a seller of the ordered traffic package, and the billing system deducts, from an account of the user, an order amount corresponding to a price of the ordered traffic package, and adds the order amount to an account of the seller; further, a billing module of the VNO platform may record a fee that is deducted from the account of the user and corresponding to the ordered traffic package.

305: The VNO platform sends the user traffic package update information including information about the ordered traffic package to a core network device, so that the core network device updates, according to the ordered traffic package, a stored traffic package of the user and a stored traffic package of the seller of the ordered traffic package, and provides a corresponding radio channel to the UE according to the updated traffic package of the user.

In this embodiment of the present invention, a user experience level may be set with five levels: level 1 to level 5. When a user experience level is 5, a user can obtain a radio channel scheduling priority with a highest level, and can experience a media service smoothly. Even when a network is congested, experience of the user in accessing the media service can still be ensured. Parameters defined in a user experience level are shown in Table 1, and include but are not limited to the following parameters: an MOS score, a bandwidth, and a scheduling priority.

Table 1 User Experience MOS Scheduling Level Score Bandwidth Priority 5 4.5 points or above 100 M High 4 4 points  50 M High 3 3 points  20 M Medium 2 2 points  10 M Low 1 1 point  5 M Low

In this embodiment of the present invention, traffic package trading of a user may include two typical situations. In a first situation, user A first buys a traffic package for a defined time period and a use location with ensured user experience, and user A sells the ordered traffic package that has been bought in advance based on such factors as whether in short supply, price fluctuations, or whether user A needs it; and user B buys the traffic package from user A. A background of trading of the traffic package is that: in a specific future time period, a large number of users will gather at a specific location (for example, a gymnasium with an ongoing event, a concert, or a hot scenic spot in holidays). Because the number of users increases sharply at the location in a specific time period, it is impossible for a wireless network to ensure experience of all users; however, an operator may prepare some traffic packages with a relatively high user experience level in advance for users in need. For example, in a gymnasium, during 19:30-21:30 (a period of an important sport event) on the evening of May 10, the operator provides 1000 10 G traffic packages with a user experience level of 4 by using 50% of air-interface resources and according to an air-interface resource capability of a wireless base station; the remaining 50% of the air-interface resources are used for access of other users, and user experience for access of these users cannot be ensured. Information that is about a traffic package with a user experience level of 4 and obtained by user A is shown in Table 2, and a price is attached when the traffic package is transferred.

TABLE 2 Traffic Package of User A Time Period 19:30 - 21:30, May 4, 2014 User Experience Level 4 Size 10 G Use Location XXX gymnasium Transfer Price HK $100

In this embodiment of the present invention, after obtaining the foregoing traffic package (possibly the traffic package is obtained by buying from an operator or buying from a virtual operator, or the traffic package is included in a monthly package, a manner of which is not limited), user A may sell the traffic package by using the VNO platform. User B may buy the traffic package from user A by using the VNO platform, and a price is negotiated by A and B. After the trading is complete, the VNO platform notifies a billing system to modify traffic packages of user A and user B (step 304 in the foregoing procedure), and notifies a core network device of the ordered traffic package (step 305 in the foregoing procedure). The use location is also recorded in the billing system and the CN (for example, a GW). After user B who bought the traffic package moves to a wireless base station corresponding to the location, the wireless network starts to provide, according to a parameter of the traffic package bought by user B and in a defined time period of the traffic package, a radio channel with a corresponding user experience level to user B.

In the foregoing trading manner, a traffic package with ensured user experience can be flexibly traded between users, so that a user really in need can obtain better service experience. In addition, after buying the traffic package from A, user B may trade the traffic package with another user according to an actual need of user B. Through this trading, 1000 traffic packages provided by an air interface with ensured user experience are circulated to users who really need them, thereby enabling reasonable resource allocation and preventing air-interface resources from being wasted.

In addition, a second situation is a trading manner based on a monthly package. Content of the trading may be learned by comparing traffic packages of user A and user B before and after the trading. For example, Table 3 shows a comparison between traffic packages of the two users before trading. User B is a common user, and a user experience level of user B is a default level (level 1 or 2) without assurance. When resources of a wireless network are limited (when the number of access users is large or in a place with network congestion), the user B may not be able to access a media service or has poor access experience (unsmooth video playback, garbling, or pausing). Prices of traffic packages are those of corresponding packages provided by an operator.

During some time periods or in some areas, user A does not need to access a media service, for example, within a month of a traffic package, user A is on a business trip, and does not need to access a media service during 8:00-10:00 in the evening, and does not need the traffic package or user experience assurance for this time period either. Then user A may transfer a 2 G traffic package during this time period by using the VNO platform. User B needs to watch a high-definition television drama in the evening this month, and happens to need a high user experience level. The two users trade the traffic package by using the VNO platform, and after the trading is complete, package information of traffic packages of the two users is shown in Table 4. After the trading is complete, a user experience level of user A becomes a default level during the period of 20:00-22:00, and a traffic package size is reduced to 8 G; correspondingly, a user experience level of user B becomes level 5 during the period of 20:00-22:00, and user B has a 2 G traffic package with a high user experience level during this period. In general, through this trading, user A transfers the 2 G traffic package with a user experience level of 5 for the period of 20:00-22:00 to user B; a price at which the two users trade the traffic package may be negotiated by themselves; and after the trading is complete, a billing system may deduct a corresponding amount from an account of user B and add the amount to an account of user A.

In this embodiment of the present invention, after a user completes ordering a traffic package on a VNO platform, when the user accesses, in a defined time period of the ordered traffic package, a media service provided by a server, the VNO platform may control in real time a radio channel for access to the media service by the user, to ensure experience of the user in accessing the media service. Referring to FIG. 4, FIG. 4 is a schematic flowchart of a radio channel control method disclosed in an embodiment of the present invention. As shown in FIG. 4, the radio channel control method may include the following steps:

401: A VNO platform collects a real-time user experience index for access to a media service (that is, access to a media service that is provided by a server, in a defined time period of an ordered traffic package) by a UE, and collects a media service transmission parameter of the media service provided by the server.

In this embodiment of the present invention, the media service transmission parameter may include a time length of the media service, an average rate (rate) of media service access, a variance of the average rate (rate variance), and the like.

402: The VNO platform determines whether the real-time user experience index is less than a user experience index defined in a user experience level of an ordered traffic package of the UE, and if the real-time user experience index is less than the user experience index defined in the user experience level of the ordered traffic package of the UE, calculates, by using the real-time user experience index and the media service transmission parameter, a radio channel parameter that is required by the user experience index defined in the user experience level.

In this embodiment of the present invention, when the radio channel parameter that is required by the user experience index defined in the user experience level is a radio channel bandwidth, the real-time user experience index and the media service transmission parameter may be used as input of a formula f(bandwith)=Bandwith_(o)+(MOS_(o)−MOS_(C))*Po*f(t, rate, rate variance), to calculate the radio channel parameter that is required by the user experience index defined in the user experience level; and when the radio channel parameter that is required by the user experience index defined in the user experience level is a radio channel scheduling priority, the real-time user experience index and the media service transmission parameter are used as input of a formula f(priority)=(MOS_(o)−MOS_(C))*Po*f(t, rate, rate variance), to calculate the radio channel parameter that is required by the user experience index defined in the user experience level, where Bandwith_(o) indicates a radio channel bandwidth defined in the user experience level, MOS_(o) indicates a user experience index defined in the user experience level, MOS_(C) indicates a real-time user experience index, Po indicates a radio channel scheduling priority defined in the user experience level, f(t, rate, rate variance) indicates an incremental calculation function, t, rate, and rate variance indicate respectively a time length of a media service, an average rate of accessing the media service, and a variance of the average rate that are included in a media service transmission parameter, f(bandwith) indicates a radio channel bandwidth that is required by MOS_(o), and f(priority) indicates a radio channel scheduling priority that is required by MOS_(o).

In this embodiment of the present invention, the real-time user experience index for access to the media service provided by a server by the UE in a defined time period of an ordered traffic package may be an MOS score calculated by the UE in real time, where the UE may comprehensively consider factors such as a cache size of the UE, a real-time rate, a packet loss rate of a media stream, and coding quality, and calculate the real-time MOS score according to these parameters.

403: The VNO platform transmits the calculated radio channel parameter to a core network device, so that the core network device adjusts, according to the radio channel parameter, a radio channel parameter used when the UE accesses the media service.

In this embodiment of the present invention, after calculating the radio channel parameter, the VNO platform may transmit these parameters to a PCRF entity of a CN in real time; after receiving these parameters, the PCRF entity may adjust in real time a radio channel parameter of a UE in a user queue of a wireless base station or a GW. In this way, experience of a user in accessing a media service can be ensured.

In the foregoing embodiment, user A sells a traffic package for a defined time period 20:00-22:00 to user B; therefore, in this time period, when user B accesses a media service by using a UE, a VNO collects, in the foregoing manner, a real-time user experience index and a media service transmission parameter when user B accesses the media service, calculates a radio channel parameter for user B when a user experience level is raised to 5, and notifies a core network device, so that the core network device can adjust in real time a radio channel parameter for access to the media service by user B. In this way, experience of a user in accessing a media service can be ensured in a defined time period of an ordered traffic package, to arouse enthusiasm for traffic trading.

In this embodiment of the present invention, after completing the traffic package trading between the two trading parties, the VNO may charge the two trading parties, where there are two billing manners, that is, non-real-time billing and real-time billing. In non-real-time billing, the VNO platform may further record billing information of the trading users, for example, account balances, lists of trading details, and lists of call details. The VNO platform may regularly send user traffic package update information including information about an ordered traffic package, in form of a payment (trading) file, to an AR of a billing system, and the AR uploads the file to a CBP to execute batch payment. In the real-time billing manner, when user A and user B complete the trading, the VNO platform may send the user traffic package update information including information about the ordered traffic package to a BMP of the billing system; after receiving the user traffic package update information, the BMP may send the user traffic package update information to the CBP; the CBP modifies account record information of the corresponding users and feeds the modified account record information back to the GW and the VNO platform.

It can be seen from the foregoing embodiment that this embodiment of the present invention can ensure, in a defined time period of an ordered traffic package, experience of a user in accessing a media service, to arouse enthusiasm for traffic trading.

Referring to FIG. 5, FIG. 5 is a schematic structural diagram of a user terminal disclosed in an embodiment of the present invention. As shown in FIG. 5, the user terminal may include a traffic trading module 51, a user experience module 52 (which mainly includes an MOS score calculating unit, a QOS calculating unit, and the like), an I/O interface module 53 (which mainly includes a touchscreen, an I/O keyboard, a microphone, and the like), a sensor module 54 (which mainly includes a gyroscope sensor, a light sensor, and other sensors), a storage module 55 (which mainly includes a memory), a processor module 56 (which mainly includes a CPU/GPU), a communications module 57 (which mainly includes a wireless cellular unit and a WLAN communications unit), and a bus 58 connecting the foregoing modules, where the traffic trading module 51 may provide a UI interface for traffic trading to a user, and provide a communications interface connected to the VNO platform.

The user experience module 52 is configured to collect a real-time user experience index (for example, a real-time MOS score) for access to a media service (which is provided by a server) by the user terminal in a defined time period of a current traffic package.

The communications module 57 is configured to: when the real-time user experience index is less than a preset user experience index, obtain a media service type of the media service provided by the server.

The traffic trading module 51 is configured to obtain a user experience level of the current traffic package and a radio resource utilization rate of a wireless base station to which the UE belongs.

The processor module 56 is configured to: when the radio resource utilization rate of the wireless base station to which the user terminal belongs is higher than a preset radio resource utilization rate, compare whether a user experience level that is required by the media service type is higher than the user experience level of the current traffic package.

The traffic trading module 51 is further configured to: when the user experience level that is required by the media service type is higher than the user experience level of the current traffic package, access a traffic trading platform (for example, a VNO platform), and actively search for a to-be-ordered traffic package meeting the user experience level that is required by the media service type.

In this embodiment of the present invention, the traffic trading module 51 may obtain the user experience level of the current traffic package from a core network device or the traffic trading platform, and obtain, from a scheduler configured for RRC of the wireless base station to which the user terminal belongs, the radio resource utilization rate of the wireless base station to which the UE belongs. The radio resource utilization rate may be a bandwidth occupancy rate of the wireless base station, or a user access rate.

In this embodiment of the present invention, by using the user terminal shown in FIG. 5, a user searches for, according to a requirement (selling a traffic package or buying a traffic package) of the user by using the traffic trading module 51 and from the VNO platform, a traffic package meeting a requirement (a requirement such as a user experience level, a use time period, and a size) to perform trading. During this process, the user terminal is an ingress to the VNO platform, and completes the trading by communicating with the VNO platform. A specific trading process includes:

1) The user starts a traffic trading module, and inputs a to-be-ordered traffic package parameter, which includes a size, a defined time period, a user experience level, and a price that are of a to-be-ordered traffic package, and may further include a use location;

2) The traffic trading module requests, from a traffic trading platform according to the input to-be-ordered traffic package parameter, a to-be-ordered traffic package in conformity with the to-be-ordered traffic package parameter;

3) The traffic trading module receives the to-be-ordered traffic package that is in conformity with the to-be-ordered traffic package parameter and sent by the traffic trading platform, and presents the to-be-ordered traffic package to the user, where the to-be-ordered traffic package parameter includes the user experience level;

4) The user selects an ordered traffic package from the traffic trading module, and feeds a selection result back to the traffic trading platform; and

5) The user confirms ordering of the ordered traffic package that is selected (including payment information confirmation), and receives an order result sent by the traffic trading platform.

In this embodiment of the present invention, the user terminal shown in FIG. 5 may further intelligently recommend to a user an ordered traffic package that can ensure experience of the user in accessing a media service. A specific recommendation process is shown in FIG. 6, and may include the following steps:

601: The user experience module collects a real-time user experience index for access to a media service provided by a server by the user terminal in a defined time period of a current traffic package.

602: When the real-time user experience index is less than a preset user experience index, the communications module obtains a media service type (for example, video, text, and music) of the media service provided by the server.

603: The traffic trading module obtains a user experience level of the current traffic package and a radio resource utilization rate of a wireless base station to which the user terminal belongs.

604: When the radio resource utilization rate of the wireless base station to which the user terminal belongs is higher than a preset radio resource utilization rate, the processor module compares whether a user experience level that is required by the media service type is higher than the user experience level of the current traffic package.

605: When the user experience level that is required by the media service type is higher than the user experience level of the current traffic package, the traffic trading module accesses the traffic trading platform, actively searches for a to-be-ordered traffic package meeting the user experience level that is required by the media service type, and reminds the user to buy the traffic package.

A scheduler and a dynamic resource allocation module are configured in an RRC of a wireless base station. In step 603 in the foregoing procedure, the traffic trading module may obtain, from the scheduler configured for RRC of the wireless base station, such information as a resource utilization rate of the air-interface, and a statistical distribution of user experience levels of all access users. For example, when a user is watching an online high-definition video, and a user experience level of the user is 3, in a time period, users accessing the wireless base station increase, so that air-interface resources of the wireless base station are in short supply, especially that the number of users with a user experience level higher than 3 increases. In this case, the wireless base station can no longer ensure that the user with the user experience level 3 continues to watch the online high-definition video. However, according to calculation (the calculation work may be completed by the wireless base station, the user terminal, or the traffic trading platform), a traffic package with a user experience level of 4 can support an online high-definition video. Then, the traffic trading module may search for, from the traffic trading platform, a to-be-ordered traffic package with a user experience level higher than 4, and recommend the traffic package to the user.

In this embodiment of the present invention, the traffic trading platform can ensure, in a defined time period of an ordered traffic package, experience of a user in accessing a media service, to arouse enthusiasm for traffic trading.

In addition, in this embodiment of the present invention, a UE may also intelligently search for a to-be-ordered traffic package whose user experience level meets the t media service type of accessed media service, to ensure experience of the user in accessing the media service, which can arouse enthusiasm for traffic trading.
